Claims priority, application Germany November 12, 1952 3 Claims. (Cl.56-314) The present invention relates to a connection of aside deliveryboard with the outside-shoe of mowing machines. The side delivery board,which is supported by the utside-shoe of the mowing beam, forms a streetin the harvested cut goods, in which street the wheels of the vehiclecarrying the mowing machine may run without running over the harvestedgoods.

It is one object of the present invention to provide a connectionbetween the side delivery board and the outside-shoe of the mowingmachine, which may be released without the use of any tools and also beeasily reinstated into its connected position.

It is of greatest importance to provide the posslblhty for easy removalof the side delivery board and for easy connection of the same inconnection with mowing machines associated with a tractor where the sidedelivery board must be removed quite often, since the tractor is usedfor other labor between the mowing periods, the bulky side deliveryboard being troublesome when not in use.

Some fast operating connections are already known for the side deliveryboard with the outside-shoe of a mowing machine which connections are,however, not very suitable for the practical mowing work, since theseknown connections include loose parts as for instance screws uponremoval of the side delivery board, which parts are subject to loss andin addition also require a change in the structure of the outside-shoes.

It is, therefore, another object of the present invention to provide aconnection of the side delivery board with the outside-shoe of themowing machine which avoids the inherent drawbacks of the knownconnections.

It is still another object of the present invention to provide aconnection of the side delivery board with the outside-shoe of a mowingmachine in which the side delivery board is secured to the outside-shoeof the mowing beam by means of a resiliently mounted latch secured tothe latter, the side delivery board being rotatable upon the said latchin order to meet the unevenness of the soil, while prevented fromfurther movement beyond the said limited rotating movement byinter-engagement between the side delivery board and the outside-shoe,the side delivery board having a notch with a slot open to the outside,and the latch of the outside-shoe springing into the notch of the sidedelivery board, thereby introducing a bolt of the outside-shoe, on whichthe resiliently mounted latch slides into the notch of the side deliveryboard, the necessary clamping of the securing head of the side deliveryboard between the outside shoe and its latch being eased by awedge-shaped formation of the portion of the side delivery boardcarrying the notch slot.

The construction in accordance with the present invention permits theconnection and disconnection, respectively, of the side delivery boardwith the outside-shoe in one single manual step, since it is merelynecessary to provide a forced turning of the side delivery board uponthe finger of the outside-shoe until the notch of the side 2,782,588Patented Feb. 26, 1957 ice delivery board disengages itself and therebyreleases the latter and in order to connect the side delivery boardagain merely the opposite single manual step is necessary. Theresistance encountered in the disengagement of the notch is adjustableby proper change of the spring force of the latch.

It is to be understood that the same result may be achieved by reversingthe provision of the latch and notch on the side delivery board and theoutside-shoe, respectively.

With these and other objects in view, which will become apparent in thefollowing detailed description, the present invention will be clearlyunderstood in connection with the accompanying drawings, in which:

Figure l is a side elevation of a securing head of a side delivery boardsecured to the end of an outsideshoe;

Fig'. 2 is a section along the lines 2-2 of Fig. 1;

Fig. 3 is a section along the lines 3-3 of Fig. 1;

Fig. 4 is an axial section through the end portion of the outside-shoe,similar to the showing in Fig. 2; and

Fig. 5 is an axial section through the side delivery board similar tothe showing in Fig. 2.

Referring now to the drawing, the outside-shoe 1 of a mowing machine hasa bolt 2 which serves as a guide for the calotte-shaped latch 3 which isforced into position by a helical spring 4. The latch 3 rests in a notch5 of complementary shape disposed in the securing head 6 of the sidedelivery board 7, as clearly shown in Figs. 1-3. In this manner the sidedelivery board is connected for relative rotatable movement with theoutside-shoe 1. In order to bring about this connection anddisconnection, respectively, with the above described construction, thenotch 5 of the securing head of the side delivery board is open to theoutside by means of the slot 8. The bolt 2 may be inserted into thenotch 5 through the slot 8, whereupon the latch 3 springs into the notch5. Since it is necessary to press manually the securing head of the sidedelivery board between the side wall of the outsideshoe and the latch 3,which is under pressure of the spring 4, in order to simplify thisconnecting step the portion of the securing head 6 of the side deliveryboard which carries the slot 8 is of wedge shape, as clearly shown inFig. 3.

The outside-shoe 1 and the securing head 6 of the side delivery boardare additionally connected by means of the finger 9 of the former, thesaid finger 9 engaging a slot 10 of the securing head with sufficientplay to permit the side delivery board to follow the unevenness of thesoil.

While the side delivery board 7 is shown in Fig. 2 on one side of thesecuring head 6, the side delivery board 7 may be disposed at theopposite side of the securing head 6, as disclosed in Fig. 5, withoutchanging the function of the device, the choice of the side beingdependent upon the material used.

In order to bring about connection and disconnection, respectively, ofthe side delivery board, it is merely necessary to turn the latter uponthe finger 9 of the outside-shoe, whereupon the latch 3 of theoutside-shoe becomes engaged and disengaged, respectively, with thenotch 5 of the securing head of the side delivery board.

The notch connection and the turning connection of the side deliveryboard with the outside-shoe may be varied and such variations are to beconsidered within the scope of the present invention, as long as thesame function and the same efiect is achieved.

While I have disclosed one embodiment of the present invention, it is tobe understood that this embodiment is given by example only and not in alimited sense, the scope of the present invention being determined bythe objects and the claims.

3 I claim: 1. An easily releasable connection of the side delivery boardwith the outside-shoe of the mowing beam of a mowing machine comprisinga latch resiliently mounted on the said outside-shoe, and the said sidedelivery board having a. notch receiving the said latch and securing thesaid side delivery board to the said outside-shoe for relative rotation,means for interengaging the said outsideshoe with the said side deliveryboard to limit the relative rotating movement to slight movements inorder to follow the unevenness of the soil, and the said notch of thesaid delivery board extendingv into a. slot leading to the outside, anda bolt extending from the said outsideshoe, and the said latch beingslidingly mounted on the said bolt, so that the said bolt may enter theslot and bring the said resiliently mounted latch into the said notch ofthe said delivery board.

2. The connection, as set forth in claim 1, in which the portion of thesaid side delivery board containing the said slot leading to the saidnotch is of wedge shape, in order to ease the insertion of the said sidedelivery 4. board between the said outside-shoe and the said latchsecured thereto.

3. The connection, as set forth in claim 1, in which the said means forinterengaging the said outside-shoe with the said side delivery boardcomprises a finger extending from the said outside-shoe and the saidside delivery board has a slot disposed adjacent the said notch, thesaid last mentioned slot receiving the said finger of the outside-shoe,the said finger being slightly movable in the said slot, so that thesaid side delivery board is permitted to follow the unevenness of thesoil by limited rotating movement upon the said bolt as pivotal axis.
